Le Baron, 8th Arr.

Concierge.com's insider take:

Just when you think this ex-bordello in the heart of the Eighth Arrondissement has had its day, it becomes popular again. There's something about the tiny space still kitted out in the louche accoutrements of its former existence (red velvet, black ceilings, fringe) that makes people want to let their hair down; the peep-show vitrines hidden away behind the stage are now empty, but the hard-dancing clientele put on their own show to the live rock and occasional electronica. The crowd is a cross-section of label-obsessives and models (and their inevitable chasers). Mick Jagger even celebrated his birthday here when he was in town.
